EB 8170

[Nilbobaggins]

About to go crazy with my restauration of a EB 8170 since I am unable to get the train of weels to align. I am begining to think that there is some part is either faulty or missing, however they all look fine under the microscope. 
 

Does anyone know what the problem could be or know where I could find a service manual? Or maybe it’s just to try over and over again util they align and spin freely?

I managed to align them alright but then the escapewheel did not spin freely and the coverplate almost looked bent. I am really confused since it is my first EB restauration and it looks fairly different to the seikos or fhf’s that I’m used to work on. 
 

Any help is much appreciated!

Always nice if you give us a picture because people might recognize it usually versus numerically or may have worked on something similar and off for some help for that.

It looks like about all of the find is the parts list at the link below. Then if you're confused by the initials that's because watch company brands are usually two or three letters which can translate into other letters used by the watch material houses. For instance the second link does have the EB and translates to the name BETTLACH Which for the purpose the material houses just the first three letters of its name.

Now it's interesting about the parts list above is nothing's been discontinued? That doesn't necessarily mean it's available but typically when I look at things there discontinued which implies this is probably something newer. Often times newer translates to know tech sheets although if we get a parts list there probably is a tech sheet someplace may be but I doubt there would be a service guide

Then the parts list came from this website

Then based on what I'm seeing these watches are cheap and they were assembled by machinery so machine would put all the gears in place in the plate would fall in place at all the pivots would go in like magic and if you try to put them in yourself anything like this is usually a real pain in the ass at least that's been my experience.

Here is the schematic diagram to EB 8170.

I'm glad you found that because it conflicts with everything else I was finding it looks like that's a standard easy to assemble Swiss lever.

The schematic states for this caliber type, I don't think it's the same.  Photos would help.

Ah sorry, forgot to attach the pictures.

Sadly I think that the schematic is wrong, as it does not look similar at all..

It could be the case that it was machine fit and therefore it is just a matter of trying again and again until it works, thanks

Unfortunately it is a cheap movement with no consideration for servicing. All you can do is keep trying. Have you tried tapping the movement holder?

That is a good tip!

 Go on to Dr ranfft's site.

See        Examples, year: signature; shock system.

it says maney calibs might have came with 8170 designation, google for the pic of each variant, Your watch might very well be 8155 or 8117,.......  but came with  8170 designation.

Diagram to each calib might not have been made available. 

 Please make a habbit of taking pix as you disassemble, for your own use and future references on this forum.
